Question

calculate the median of the following : first 40 whole numbers​

Answer 1

Sum of first n natural numbers=n(n+ 1)/2. So,sum of 40 natural numbers=(40*41)/2=820. Therefore the required average=820/40=20.5

Answer 2

Step-by-step explanation:

whole no.s -

0,1,2,3,4,5,6,7,8,9,10,11,13,14,15,16,17,18,19,20............................................,40

they are total 41 no.s (from 0-40) so they are odd

so the median will be 20
